In freezing temperatures the power antenna on my '94 Accord LX is
often stuck because of the plastic strip that moves the antenna telescop
is just not able to handle the extra friction. Since I still want to use
my mp3 player through the radios FM band under those conditions, I'd
like to splice in a toggle switch in the line that sends the "radio-on"
signal to the antenna servo.
From what I see in the wiring diagram, the servo motor gets both a
constant +12V voltage and a "radio-on" 12V (?) on two separate lines (in
addition of Ground) and from that I gather that the radio-on voltage
supplies low signal power only to a relay that then applies the constant
12V power to the motor. So, it's pretty obvious that the toggle switch
should be installed serially in the radio-on line. What is not obvious
to me is from the wiring diagram just where the best place in that line
would be because I can't see where that line originates under the
dashboard. Has any of you installed such a switch and can lend me a hand
in this?
